Module: Puppet::Indirector

Overview

Manage indirections to termini. They are organized in terms of indirections -

  • e.g., configuration, node, file, certificate – and each indirection has one

or more terminus types defined. The indirection is configured via the indirects method, which will be called by the class extending itself with this module.

Instance Method Details

#indirects(indirection, options = {}) ⇒ Object

Declare that the including class indirects its methods to this terminus. The terminus name must be the name of a Puppet default, not the value – if it's the value, then it gets evaluated at parse time, which is before the user has had a chance to override it.

Raises:

  • (ArgumentError)
